I would also agree that MUCH more foliage, cover, and branches is needed in this enclosure.
I would also suggest losing the fake flowers, as veileds are known to eat flowers and vegetation from time to time and you don't want your cham to try and eat a fake flower as this could lead to BIG problems of both digestion and impaction in it's digestive tract.
UVB lighting is also hugely important in all chamleons, so make sure to invest in a good UV bulb like a Reptisun 5.0 or Arcadia too.
